JADA study outlines repairs for chipped restorations
The usage of porcelain restorations among dentists, whether porcelain-fused-to-metal or all-ceramic, inevitably leads to cases of chipped restorations. Researchers from the New York University College of Dentistry and the University of Maryland School of Dentistry have completed a study that dentists in such situations may find useful. In this literature review, the researchers examined how frequently chipping occurs in certain systems and why it happens. The second aspect of the study explored the various means and strategies for repairing chipped porcelain restorations. They also had recommendations for working with different materials.

Study: Tooth loss due to periodontal disease more prevalent among postmenopausal women
The Medical News
Postmenopausal women who have smoked are at much higher risk of losing their teeth than women who never smoked, according to a new study published and featured on the cover of the Journal of the American Dental Association by researchers at the University at Buffalo. The study involved 1,106 women who participated in the Buffalo OsteoPerio Study, an offshoot of the Women's Health Initiative, the largest clinical trial and observational study ever undertaken in the U.S., involving more than 162,000 women across the nation, including nearly 4,000 in Buffalo, N.Y.More

Fluoride to be added back into Pinellas County, Fla., water
Water fluoridation resumed March 1 for Pinellas County, Fla., water customers, as well as customers of Clearwater, Pinellas Park, Safety Harbor and Tarpon Springs. In October 2011, county commissioners voted to end the practice of adding fluoride into the area's drinking water. The decision caused a heated debate among residents and led to a couple of cities, including St. Petersburg and Dunedin, to continue adding fluoride despite the decision. Then, just over a year later, Pinellas County commissioners voted to put fluoride back into the water.More

Alcohol consumption increases oral cancer risk for men
Dentistry Today
Oral cancer risk in men goes up significantly as a result of alcohol consumption, according to a new study. The American Journal of Public Health study indicated that there are about 20,000 deaths each year in the United States that stem from cancer. Men are at the largest increased risk for oral cancer while breast cancer risk in women goes up based on alcohol consumption.More

Gains made toward treatment of rare bone disease
Diagnosed in toddlers, X-linked hypophosphatemia is the most common form of heritable rickets, in which soft bones bend and deform, and tooth abscesses develop because infections penetrate soft teeth that are not properly calcified. Researchers at McGill University and the Federal University of Sao Paulo have identified that osteopontin, a major bone and tooth substrate protein, plays a role in XLH. Their discovery may pave the way to effectively treating this rare disease.More

IOM workshop examines oral health literacy
American Dental Association
Limited oral health literacy is associated with inaccurate knowledge about preventive measures such as water fluoridation, dental care visits and oral health-related quality of life, the policy advisory Institute of Medicine said in a report. "For example, nationally only '44 percent of adults with less than basic health literacy skills had a dental visit in the preceding year compared with 77 percent of those with proficient health literacy skills.'"More

Underlying mechanisms behind chronic inflammation-associated diseases revealed
Inflammatory response plays a major role in both health protection and disease generation. While the symptoms of disease-related inflammatory response have been know, scientists have not understood the mechanisms that underlie it. In a paper published Feb. 21 in Cell Reports, a team lead by Xian Chen, associate professor of biochemistry and biophysics and member of the UNC Lineberger Comprehensive Cancer Center, mapped the complex interactions of proteins that control inflammation at the molecular level.More

Research shows the potential dental health risk of fruit smoothies
Health Imaging Hub
A new laboratory study of the erosive potential of fruit smoothies on teeth has been published in the latest issue of the British Dental Journal. The authors of the BDJ report, "In vitro investigation of the erosive potential of smoothies," maintain that encouraging healthier eating habits, including five portions of fruit and vegetables a day, could inadvertently promote damage to teeth if beverages such as fruit smoothies are regularly consumed as fruit and vegitable substitutes outside of mealtimes.More

Too many toothaches taking over ERs
It is hard to ignore a bad toothache, but thousands of Georgians are putting off getting help until the pain become unbearable. They instead are turning to emergency rooms to provide relief. It is not just a trend in Georgia, but across the nation driven by a few factors. About a third of all Americans do not have any dental insurance coverage and unlike ERs, dentists are not required by law to treat patients with dental emergencies if the patient cannot pay. Health experts say the ER is not the answer.More

Cataloging healthcare's excesses
The New York Times
The cover story in Time magazine "Bitter Pill: Why Medical Bills Are Killing Us" is a serious, exhaustively reported piece about the problem the U.S. healthcare system has become. The article, by Steven Brill, has created unusual buzz in Washington; it spares no vested interest. Nonprofit hospitals, the cornerstone of many communities, capriciously overcharge patients, sticking the powerless with exorbitant bills, while paying lavish salaries to their executives; drug companies, which charge humongous markups to American customers, rake in huge profits; trial lawyers, with the threat of legal action, add to the cost of defensive medicine; President Barack Obama's Affordable Care Act does little to bend the cost curve, and while conservatives rail against Medicare, the government-run insurance program is more efficient and customer-friendly than the private system.More

How drug companies distort science: Q&A with Ben Goldacre
Think your doctor gets all the scientific evidence on a drug before it gets to market? Not necessarily. Half of the research data on drugs is not readily available to physicians, as the U.K.'s Ben Goldacre reveals in his book "Bad Pharma: How Drug Companies Mislead Doctors and Harm Patients." He discussed the problem — and proposed some potential solutions.More
